What is Transradial Amputation?

Transradial amputation is a surgical procedure in which the forearm is amputated below the elbow joint, through the radius and ulna bones. It is one of the most common upper-limb amputation levels because it preserves elbow function, which is critical for daily activities and prosthetic use. This level of amputation allows patients to retain better control, strength, and range of motion compared to higher-level amputations.

Transradial amputation may be performed due to trauma, severe infection, cancer, congenital abnormalities, or irreversible vascular disease. From a rehabilitation perspective, this amputation level offers favorable outcomes, as patients can often adapt well to prosthetic devices. Modern prosthetics, including myoelectric hands, work particularly well with transradial amputations because remaining muscles can still generate useful control signals.

Technique

The surgical technique for transradial amputation focuses on preserving as much functional length as possible while ensuring proper wound healing and prosthetic fitting. Surgeons carefully plan skin flaps to provide durable coverage and shape the residual limb. Muscles are stabilized and attached to opposing structures (myodesis or myoplasty) to maintain strength and reduce muscle atrophy.

Special attention is given to nerve handling to prevent painful neuromas. Major nerves are gently pulled down, cut under tension, and allowed to retract into soft tissue. The radius and ulna are trimmed smoothly, and bone edges are rounded. Proper technique is essential to create a comfortable, well-shaped residual limb that supports long-term prosthetic use and minimizes complications.

Meaning

The meaning of transradial amputation lies in its anatomical location. The term “transradial” combines “trans,” meaning across, and “radial,” referring to the forearm bones. Clinically, it indicates an amputation that occurs through the forearm rather than at the wrist or above the elbow.

In practical terms, this amputation level is considered a balance between removing diseased or damaged tissue and preserving function. Patients often retain excellent elbow motion and can perform many daily activities independently with or without a prosthesis. Understanding the meaning helps patients and caregivers better grasp the goals of surgery and rehabilitation.

Definition

By definition, a transradial amputation is the surgical removal of the hand and part of the forearm through the radius and ulna, below the elbow joint. It is classified as a partial upper-limb amputation and is distinct from transhumeral (above-elbow) amputations.

This definition is important in medical documentation, prosthetic planning, and rehabilitation protocols. The level of amputation directly affects prosthetic selection, functional expectations, and long-term outcomes. A clearly defined transradial level allows healthcare teams to design individualized treatment and rehabilitation plans.

Right Forearm Transradial Amputation

A right forearm transradial amputation involves removal of the right hand and part of the right forearm. This can significantly affect daily activities, especially for right-hand-dominant individuals. Tasks such as writing, eating, and fine motor activities may require adaptation or prosthetic assistance.

Rehabilitation focuses on restoring independence through occupational therapy and prosthetic training. Many patients successfully use myoelectric or body-powered prostheses on the right side, regaining functional grasp and control. Early therapy and proper prosthetic fitting play a crucial role in achieving optimal outcomes.

Left Forearm Transradial Amputation

A left forearm transradial amputation affects the non-dominant hand in many individuals, which may slightly reduce functional impact compared to dominant-side amputations. However, challenges still exist, particularly in bimanual tasks that require coordination between both hands.

Patients with left-sided transradial amputations often adapt well with targeted rehabilitation and assistive devices. Prosthetic use can significantly improve symmetry and function, especially in tasks requiring stabilization or support. With proper care, individuals can return to work, hobbies, and daily routines with minimal limitations.
